TECHNICAL FIELD

Embodiments of this application relate to the field of heat-not-burncigarette device technologies, and in particular, to a vapor generationdevice and a susceptor.

BACKGROUND

Tobacco products (such as cigarettes, cigars, and the like) burn tobaccoduring use to produce tobacco smoke. Attempts are made to replace thesetobacco-burning products by making products that release compoundswithout burning.

An example of this type of products is a heating device that releasescompounds by heating rather than burning materials. For example, thematerials may be tobacco or other non-tobacco products. Thesenon-tobacco products may include or not include nicotine. As anotherexample, the related art provides a heating device of an electromagneticinduction heating type. A structure of the heating device is shown inFIG. 1 . When a tobacco product 1 is accommodated in the heating device,a susceptor 2 is penetrated by an alternating magnetic field generatedby an induction coil 3 to inductively generate heat, thereby heating thetobacco product 1. During heating, for convenience of monitoring aheating temperature of the tobacco product 1 in real time, the heatingdevice adopts a temperature sensor 4 that is closely attached to thesusceptor 2 to sense a real-time operating temperature of the susceptor2. The heating device adjusts parameters of the alternating magneticfield generated by the induction coil 3 based on a sensing result of thetemperature sensor 4, so that the susceptor 2 is within an appropriateheating temperature range.

During implementation of foregoing temperature detection by thetemperature sensor 4, on the one hand, the temperature sensor 4 isusually made of a thermistor metal material and will generate heat byitself in the alternating magnetic field. On the other hand, thetemperature sensor 4 made of metal materials and the susceptor 2 eachgenerate an induced current, which affects a sensing signal outputted bythe temperature sensor 4, thereby affecting the accuracy of the sensingsignal.

The cylindrical inductancecoil L wound into the spiral shape may have a length ranging from about8 mm to about 14 mm, and the number of turns of the inductance coil Lmay range from 8 to 15. Correspondingly, an inner volume may range fromabout 0.15 cm³ to about 1.10 cm³.

In a more exemplary implementation, a frequency of the alternatingcurrent supplied by the circuit 20 to the inductance coil L ranges from80 KHz to 400 KHz, and more specifically, the frequency may range fromabout 200 KHz to 300 KHz.

In an exemplary embodiment, the direct-current voltage supplied by thecore 10 ranges from about 2.5 V to about 9.0 V, and the direct currentsupplied by the core 10 ranges from about 2.5 A to about 20 A.

In an exemplary embodiment, the susceptor 30 in FIG. 2 is made of ametal or an alloy material with an appropriate magnetic conductivity, sothat when used, the susceptor 30 can inductively generate heatcorresponding to the magnetic field to heat the accommodated inhalablematerial A to generate the aerosol for inhaling. The susceptor 30 may bemade of grade 420 stainless steel (SS420), and an alloy material (suchas J85/J66 permalloy) containing iron and nickel.

In the embodiment shown in FIG. 2 , the vapor generation device furtherincludes a tubular holder 40 configured to arrange the inductance coil Land mount the susceptor 30. The tubular holder 40 may be made of ahigh-temperature resistant non-metal material, for example, PEEK,ceramic, or the like. During implementation, the inductance coil L isarranged on an outer wall of the tubular holder 40 in a spirally woundmanner, and at least a part of the tubular holder 40 is internallyhollow to form the cavity configured to accommodate the inhalablematerial A.

Referring to FIG. 3 and FIG. 4 together, the susceptor 30 includes: afirst part 31 constructed in a blade shape extending in an axialdirection of the cavity, and a second part 32 constructed to be a pin orin a needle shape extending in the axial direction of the cavity. Inaddition, during implementation, the first part 31 has a vacancy 311extending in the axial direction, and the second part 32 is held in thevacancy 311. During use, the first part 31 and the second part 32 may besimultaneously inserted into the inhalable material A and then heat theinhalable material A.

Referring to FIG. 4 and FIG. 5 together, based on an idea of accuratelydetecting a temperature of the susceptor 30, the second part 32 is ahollow structure in which an accommodation cavity 321 extending in theaxial direction is arranged. During use, the accommodation cavity 321 isconfigured to accommodate and encapsulate a temperature sensor 50.Certainly, after fixed in the accommodation cavity 321, the temperaturesensor may be encapsulated inside the second part 32 by gluing, and thelike, and is closely attached to an inner wall of the second part 32, soas to accurately detect a real-time operating temperature of thesusceptor 30.

Referring to FIG. 3 and FIG. 4 again, for ease of mounting and fixingthe susceptor 30, the susceptor further includes a base part 33. Thefirst part 31, the second part 32, and the base part 33 are fixed as anindivisible integral by soldering, interference fitting, or the like.During use, the base part 33 is constructed into a plate perpendicularto the first part 31 and the second part 32, and has a size greater thanthat of the first part 31 and the second part 32, so as to be mountedand fixed in the tubular holder 40 by abutting, clamping, and the like.

Meanwhile, the base part 33 has a through hole 331 configured for aconductive pin 51 of the temperature sensor 50 to run through and beexposed outside the susceptor 30, so that the conductive pin 51 iselectrically connected to the circuit 20 to supply power and receive asensing signal.

It may be learnt from FIG. 3 and FIG. 4 that, a size of an outerdiameter of the second part 32 is greater than a thickness of a sheet ofthe first part. Therefore, the second part 32 can protrude from twosides of the first part 31 in a thickness direction, so that thesusceptor 30 can have a relatively larger surface area to be in contactwith the inhalable material A, thereby increasing the efficiency of heattransfer during heating.

In some embodiments, meanwhile, in order to avoid heat damage of thetubular holder 40 caused by heat transfer from the base part 33 to thetubular holder 40, the base part 33 is made of a material with a lowthermal conductivity, for example, zirconia ceramic, and the like.

In some embodiments, the first part 31 and the second part 32 may befixed by close fitting, and the like.

Referring to FIG. 6 , in some embodiments, an outer surface of a secondpart 32 a is provided with grooves 322 a extending in the axialdirection. A first part 31 may be integrated with the second part 32 aby being embedded into the grooves 322 a to be clamped.

Referring to FIG. 7 , in some embodiments, for ease of detaching andreplacing a susceptor 30 b, after a temperature sensor (encapsulated inthe susceptor 30 b and not shown) is encapsulated in the second part 32a through a through hole 311 b of a base part 33 b, a conductive contact51 b which is exposed outside an outer surface of the susceptor 30 b isformed on a surface of the base part 33 b by printing, printing,depositing, or etching, and is configured to be connected to a pin ofthe temperature sensor by soldering, and the like. During use, thecircuit 20 may abut against the conductive contact 51 b by a contactconductive mechanism such as a commonly used conductive elastic pin, tosupply power to the temperature sensor or receive a sensing signal, soas to avoid inconvenience caused to the replacing and detaching of thesusceptor 30 by soldering the pin of the temperature sensor to thecircuit 20.

Referring to FIG. 8 and FIG. 9 together, in some embodiments, asusceptor 30 c is constructed into a blade shape, and has a first end 31c and a second end 32 c. The first end 31 c is opposite to an opening ofthe cavity configured to accommodate the inhalable material A. Duringuse, the first end 31 c, as a free end, is constructed into a tip shapefor being easily inserted into the inhalable material A that isaccommodated in the cavity through an opening end. The second end 32 c,as an end portion for mounting and connecting, is configured to providesupport through the tubular holder 40, so that the susceptor 30 c isstably held and fixedly mounted in the device.

In some implementations, the construction of the susceptor 30 c isformed by a first sheet-like object 310 c and a second sheet-like object320 c that are opposite to each other in the thickness direction.Specifically, the first sheet-like object 310 c includes a flat andstraight first part 311 c, a second part 312 c formed by the first part311 c protruding outward in the thickness direction, and a third part313 c formed by at least a part of the first part 311 c close to thesecond end 32 c extending in a width direction. Correspondingly, a shapeof the second sheet-like object 320 c is similar to that of the firstsheet-like object 310 c. The second sheet-like object 320 c also has aflat and straight fourth part 321 c, a fifth part 322 c formed by thefourth part 321 c protruding outward in the thickness direction, and asixth part 323 c formed by at least a part of the fourth part 321 cclose to the second end 32 c extending in the width direction. After thefirst sheet-like object 310 c and the second sheet-like object 320 c arecombined, an accommodation cavity 330 c configured to accommodate andencapsulate a temperature sensor 340 c is formed between the twosheet-like objects. Specifically, the accommodation cavity 330 c isformed by a first recessed structure 331 formed by the second part 312 cof the first sheet-like object 310 c, and a second recessed structure332 c formed by the fifth part 322 c of the second sheet-like object 320c.

During assembling, a sensing part 341 c of the temperature sensor 340 cis accommodated and encapsulated in the accommodation cavity 330 c, andmay be encapsulated and fixed by gluing, and the like. Meanwhile, anelectrical connection part 342 of the temperature sensor 340 c isdesigned into a long and thin pin and runs through the second end 32 cfrom the accommodation cavity 330 c to the outside of the susceptor 30c, so as to be conveniently connected to the circuit 20. Then, thecircuit 20 may receive a sensing signal of the sensing part 341 cthrough the electrical connection part 342. During use, the temperaturesensor 40 is encapsulated in the accommodation cavity 330 c that isoverall insulated from a magnetic field. The sensing part 341 c closelyabuts against the first sheet-like object 310 c and/or the secondsheet-like object 320 c. In this way, a temperature of the susceptor 30c can be detected stably or accurately while avoiding interference bythe magnetic field.

Furthermore, the temperature sensor 340 c may be a thermistortemperature sensor that calculates the temperature by monitoring achange of resistance, for example, PT1000, or may be a thermocoupletemperature sensor that calculates the temperature by calculatingthermo-electromotive forces at two ends.

Based on an idea of mass production and preparation of the susceptor 30c, furthermore, in an exemplary implementation, the second part 312 c ofthe first sheet-like object 310 c and/or the fifth part 322 c of thesecond sheet-like object 320 c are/is formed or prepared by stamping onthe foregoing flat sheet-like sensing material, such as a sheet metalpart. Meanwhile, in a stable connection, the first sheet-like object 310c and the second sheet-like object 320 c may be integrated by soldering,such as, laser soldering, and the like.

In some embodiments, the accommodation cavity 330 c extends in an axialdirection of the susceptor 30 c. During implementation, a cross sectionof the accommodation cavity 330 c may generally be in a diamond shape, acircle shape, a square shape, or the like.

As shown in FIG. 9 , the second part 321 c has a conical part 312 c 1that is close to the first end 31 c of the susceptor 30 c and whosecross-sectional area gradually decreases, for example, a circular cone,a triangular cone, or the like. The conical part 312 c 1 is configuredto reduce resistance when inserted into the inhalable material A.

In some embodiments, the conical part 312 c 1 of the second part 312 c,together with the corresponding fifth part 322 c that has a similarstructure, may cause a front part of the formed accommodation cavity 330c close to the first end 31 c to be in a cone shape. During mounting,the sensing part 341 c of the temperature sensor 340 c abuts against thecone-shaped front part of the accommodation cavity 330 c, for ease ofclose fitting and mounting.

According to the embodiment shown in the figure, in the susceptor 30 c,a size of the accommodation cavity 330 c formed by the second part 312 cand the fifth part 322 c in the thickness direction is greater thanother part of the susceptor 30 c. Meanwhile, a size of thickness of theaccommodation cavity 330 c formed by the second part 312 c and the fifthpart 322 c gradually increases inward in the width direction, so that anouter surface of the susceptor 30 c formed by the second part 312 c andthe fifth part 322 c gradually changes. On the one hand, a contact areawith the inhalable material A is increased to improve the efficiency ofheat transfer. On the other hand, the resistance is reduced when thesusceptor 30 c is inserted into the inhalable material A.

Referring to FIG. 10 and FIG. 11 together, in another embodiment, asecond sheet-like object 320 d/320 e of a susceptor 30 d/30 e is flatand straight. A second part 312 d/312 e protruding outward in thethickness direction is formed only on the second sheet-like object 310d/310 e by stamping, or the like. An accommodation cavity 330 d/330 econfigured to accommodate or encapsulate a temperature sensor is formedbetween the second part 312 d/312 e and the second sheet-like object 320d/320 e.

According to the embodiment shown in FIG. 5 or FIG. 6 , a cross sectionof the second part 312 d/312 e may generally be in a triangle shape or acircular arc shape whose size of thickness gradually increases inward inthe width direction. It may be seen from FIG. 5 and FIG. 6 that a sizeof protruding of the second part 312 d/312 e in the thickness directionis greater than a size of thickness of a first part 311 d/311 e.

Referring to FIG. 12 , in another embodiment, along a susceptor 30 f, athird part 313 f of a first sheet-like object 310 f of the susceptor 30f has a size of thickness greater than that of a first part 311 f and asecond part 312 f. In this way, the third part 313 f protrudes relativeto other parts in the thickness direction, so as to be easily mounted orheld in the device.

The vapor generation device and the susceptor of this applicationencapsulates or accommodates the temperature sensor in the susceptor. Inthis way, on the one hand, a sensing part may be basically insulatedfrom the impact of the magnetic field, and on the other hand, thesusceptor and the temperature sensor may be integrated to increase thestability of mounting and the accuracy of temperature detecting, andmeanwhile, overall replacement and mounting are easier.

This application further provides a method for preparing the foregoingsusceptor 30 c. Referring to FIG. 13 , steps of the method include:

S10: Provide a first sheet-like object 310 c and a second sheet-likeobject 320 c that are opposite to each other in a thickness direction;
